Daniels MT-4 product line is separated into base and repeater modules.
There is different hardware, fi rmware and software for the base and
repeater modules. MT-4R modules are all repeater modules, so no
distinction between base and repeater is made. MT-4D modules
are referred to as either MT-4D Repeater modules or MT-4D Base
modules.
The MT-4D Repeater modules are capable of being connected in
a repeater confi guration or a base station confi guration with no
encrypting / decrypting capability (clear mode). MT-4D Base modules
must be used when encryption capability (secure mode) in a base
station confi guration is required. MT-4D Base modules have limited
repeat capability using analog audio paths. The analog audio repeat
path does not pass all digital information through the repeater (such
as NAC, TGID, encryption and data packets).

Being able to identify the series of MT-4 P25 module that you have is
critical for programming, and understanding capabilities and operation
of the equipment. The model number of the P25 receiver or transmitter
can be found on the bottom of the front panel of the receiver or
transmitter module as shown in Figure 1-1. Figure 1-2 and 1-3 show
the breakdown of the receiver and transmitter model numbers.
